CEILING-SLEEVE ATTACHMENT.

Application mediu 7, 1923. Serial a... 637,291;

Be it known that 1, CHARLES J. PETRAsnK, acitizen of the United States, residing at New Lebanon, in the county vof Columbia and'State of New York, haveinvented certain new and useful Improvements moan ing-Sleeve Attachments, of which the following is a specification. t v

; This invention relates to steam fitting appliances or the like and has particular reference to what are commonly called ceiling sleeves fitted loosely around steam or hot water pipes so as to serve among other purposes to hold the pipe temporarily in place from lateral movement while the plaster or equivalent finishing devices are applied to the. building and also to permit vertical movement of'the pipe due to expansion and contraction.

In the usual practice the sleeve, of substantially thesame general character as the sleeve shown herein, i held in lace by means of two or more metal straps attached to its upper end, the straps being extended toward or over the upper edge portions of the adjacent floor beams and there nailed by a workman on the upper floor. Another workman or a helper, however,.is required beneath the floor at which the fittting is being done in order to determine as nearly as possible the precise elevation or location of the sleeve. The result is that not only are two men required for this purpose b-ut there is difficulty in determining the proper location for the sleeve with respect to the ceiling plaster that co-operates with it and also to maintain the desired po sition after it is established clue to the fact that any lateral movement of the pipe serves to swing the sleeve upward as well as laterally, around the points of attachment of the metal straps as centers.

Among the objects, therefore, of this improvement is to facilitate the placing of the sleeve at any desired distance between the floor beams or relation to either of the adjacent beams and also with respect to the ceiling line or plane; to enable a workman not only to do the work alone, but that he may adjust the sleeve much more reliably than could be done by two men as practised heretofore; to accomplish the result desired with the least expenditure of time and effort on the part of the workman; to provide a construction or fastening means which in itself constitutes lathing for the direcet plication of the coating of plaster, andialso serving to constitute a support for a filling of concrete. or the like between the adorbeams or their equivalent when fireproof construction is used. I

With the, foregoing and other objects in view the invention consistsin the arrangement'and combination of parts hereinafter described and claimed, and while the inven-,

tion is not restricted to "the exact details of construction disclosed or .sugge sted herein, still for the purpose of illustrating a practical embodiment thereof referenceis had to the accompanying drawings, in which like reference characters designate the same parts in the several views, and in which Figure 1 is a vertical sectional view showing diagrammatically the application of one form of the, device. Q

.R-eferring now more specifically to, the drawings the sleeve 10 is' shown conical. 0r tapered and is of sheet metal, open at both ends according to the diameter of the pipe or riser 11 and so having no clearance as heretofore for collection of dirt, plaster or,

the like at the top. At the lower end the sleeve 10 is fitted with an ornamental cap 13 attached in any suitable manner and having a more restricted opening 14: fitting fairly close around the pipe and hence of constructions it is not uncommon for the plaster tobe applied either above the cap' or soas to cover more or less of it, making in either event an unsightly finish. From By my improvement the tapered form of the sleeve it follows that the cap will always lie in a perfectly level position perpendicular to the axis of the pipe. I p

15 indicates a sheet or strip of wire mesh material of any suitable construction, such as woven wire or stamped meshwork such as is suitable for use as metal lathing. This strip is of a length suitable to more than span two adjacent floor beams 16 so that while provided with a hole 17 nearer one endthan the other of the strip, the end portions of the strip or support may be fastened to the bottoms of the adjacent beams irrespective of the spacing of the pipe between the beams. Assuming for instance, that the beams are 12 inches between centers the strip 15 should measure approximately 8 inches from one end to the center of the hole 17 while'the other end portion may be 12 inches long. By this arrangement if the pipe comes midway between the beams, the shorter end of the strip may be nailed directly against the bottom of one beam while the other end portion may pass beyond the other beam and be nailed against one side thereof. On the other hand, if the pipe should come close to one of the beams, the longer end of the strip still would be long enough to reach the remote beam while the shorter end would fasten around the nearer beam as indicated in Fig. 1. "While ordinarily the strip 15 is provided with only one hole 17 I indicate at 17 the expedient of. forming therein more than one hole for the accommodation of more than one pipe at the same installation. Bounding the hole 17 the sleeve support or strip 15 is provided with a downwardly turned flange 18 through which the sleeve is projected and fastened securely as by rivets 19. The space between the support 15 and the capmay be three-fourths of an inch or thereabouts' according to the charactor of the plaster or other finishing1naterial. The device thus far described is a complete unit and assembled preferably at the factory. In use the sleeve is slipped over the riser at the time the latter is erected, in the usual manner, and when the location of the riser is approximated the workman charged with the duty of making the connections will simply pass the sleeve upward, bringing it into proper position as above described and fastening it by nails or tacks as indicated at 20. This is easily accomplished and there can be no question as to the proper elevation of the sleeve and cap. Moreover, the support 15 is so strong that there can be no possibility of the pipe tilting or moving laterally after the support is attached as stated. Again, plaster as indicated at 21. may be applied directly to the strip 15 the same as any other metal lath, and therefore the work of lathing and applying the plaster is materially reduced and expedited. I also The form of the device as shown in- Figs.

4 and 5 differs from that above described in that the sleeve 10 is punched along its sides with pairs of holes 23 in or through which wires 15 are looped and fastened as by twisting at 24, an expedient that is rapid and cheap. The elevation of these wires above the cap, as in the other formof the device, is about the same as the thickness of the lath and plaster for the ceiling.

The installation or application of this sleeve to the pipe and floor beams is in general similar to that above described. After the pipe is located the sleeve is slipped up to place to an elevation easily determined to be proper and then the wires 15- are snubbed or otherwise fastened by suitable fasteners such as nails 25 driven into the beams. These nails may readily be driven into the bottom edges of the beams or on the remote sides thereof from the'pipe. The space around the nail heads is then covered with lath 26 and plaster 21 as indicated, or any other suitable ceiling material may be applied. In both forms of the device the pipe is not only properly positioned and held in place but is free to expand or contract lengthwise of the sleeve without interference with the floor construction or ceiling. V

'The tapering of the sleeve 10 makes it practically impossible for any dirt, cement, or other foreign matter to drop into and lodge within the sleeve and therefore it is unnecessary for the upper end of the sleeve to bepackedwith paper, rags, or the like as is now the. usual practice. Moreover, since the smaller upper end of the sleeve fits practically close around the pipe, this end together with the escutcheon makes it impossible for the sleeve to tilt with respect to the axis of the pipe and therefore the cap will always maintain a proper level position with respect to the other parts of the work.

I claim:

A device of the character described, comprising a truncated sleeve, a-truncated cap on the lower end of the sleeve, the upper slnaller'end of thesleeve and the cap having alignedopenings of the same size to fit a pipe to be positioned therethrough, and 7 2.
